Be careful about terminology! Objects are not protected by roles
(but by permissions).
You gain something if a near local role grants the necessary
The "Owner" local role tends to be very near.
Thus, you may gain, when usually owners try to execute protected

Nobody prevents you to implement your "allowed" by means
